Hierarchical Modeling and Hybrid Performance Evaluation of a Micro-Mobility Architecture for IP Networks

T. JohnsonR. PradoE. ZagariT. BadanE. CardosoL. Westberg

Micro-mobility protocols aim to improve localized mobility by reducing the handover overhead. The Mobility Plane Architecture was designed to support micro-mobility in standard IP or MPLS/GMPLS networks in a networkcentric way. This paper presents the QN models representing the architec- ture’s procedures, including node attachment, node updating and handover. Results show it is necessary to consider the type of mobile node when evaluating a micro-mobility scenario. Hardware and software aspects may affect the node’s interaction with the micro-mobility protocols. The results show the importance of considering L2 and L3 association times because they can affect all procedures involving new associations.
